We look at the division of 70011803 by 647 
The aim is to understand the frequency of 647 in 70011803.

Advancing to step 1:
When dividing 7 by 647, we get 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 647

Step 2:
When dividing 70 by 647, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 70 to get 70.
Take the next digit (0) from the dividend and append it to 70, then repeat: 700 / 647

Moving on to step 3:
The number 647 fits into 700 1 times, leaving a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 647 from 700, we get 53.
Fetch the next digit (1) from the dividend, attach it to 53 and continue: 531 / 647

Advancing to step 4:
647 goes into 531 0 times with a remainder of 531.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 531 after subtracting 0 from 531.
Include the next digit (1) from the dividend after 531, then repeat: 5311 / 647

Moving on to step 5:
5311 divided by 647 is 8 with a remainder of 135.
The number 8 becomes the next digit in our result. 
Result so far: 108.0
Subtract 5176 from 5311 to get 135.
Fetch the next digit (8) from the dividend, attach it to 135 and continue: 1358 / 647

Going ahead to step 6:
The number 647 fits into 1358 2 times, leaving a remainder of 64.
Write down 2 as next digit of the result. 
Result so far: 1082.0
If we take 1294 away from 1358, we end up with 64.
Take the next digit (0) from the dividend and append it to 64, then repeat: 640 / 647

Moving on to step 7:
640 divided by 647 is 0 with a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 10820.0
Deduct 0 from 640 and we're left with 640.
Grab the next digit (3) from the dividend, add it to 640, then carry on: 6403 / 647

Let's proceed to step 8:
When dividing 6403 by 647, we get 9 with a remainder of 580.
Record the quotient 9 as the next digit in the result. 
Result so far: 108209.0
Deduct 5823 from 6403 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 9:
When dividing 5800 by 647, we get 8 with a remainder of 624.
The next digit of our result is 8. 
Result so far: 108209.8
Subtracting 5176 from 5800 leaves us with 624.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6240, and continue the process.

Step 10:
If we divide 6240 by 647, we get 9 and a remainder of 417.
Put 9 as the next digit of the answer. 
Result so far: 108209.89
If we take 5823 away from 6240, we end up with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

On to step 11:
647 goes into 4170 6 times with a remainder of 288.
Put 6 as the next digit of the answer. 
Result so far: 108209.896
Deduct 3882 from 4170 and we're left with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

On to step 12:
When dividing 2880 by 647, we get 4 with a remainder of 292.
The number 4 becomes the next digit in our result. 
Result so far: 108209.8964
If we subtract 2588 from 2880, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Going ahead to step 13:
The number 647 fits into 2920 4 times, leaving a remainder of 332.
The next digit of our result is 4. 
Result so far: 108209.89644
Subtract 2588 from 2920 to get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

After the division, we end up with 108209.89644 and a remainder of 0.000332.
